After using phar more vowels and consonants than a Mephisto crossword, and dizzying algebraic formulae which leave my mathematical age of six spinning, it comes down to this: no, money can't guarantee results.
I could put up my first venture with Songsheet to demo that theory. We bought a RELAUNCH mare i/f to AGNES WORLD, then standing for £65,000. This bought what Venusian was to ascribe as 'probably the worst horse in training', the useless WORLDWIND, who took until four years of age to get even slightly raceworthy, before disgracing her genes with a debut and second run (Laura and Ian Mongan know when to pull the plug) seeing her come last, some 30l off the penultimate finisher. AW had pulled in over $2m in prize money, looked gorgeous - and proved a fiasco ever since, with the slight exception of the AW stalwart CODA AGENCY (David Arbuthnot), who I think has now been retired. QED.
